MC34SB0800 Octal Valve and Pump Controller Block Diagram


Supply voltage

  • Up to 36V

Low Side Drivers (x8)

  • Four Low side Drivers Regulated up to 2.25A
  • +/-2.0% precision reachable with calibration
  • Four Low side Drivers PWM up to 5kHz with a maximum current capability up to 5A
  • All Low Side Drivers are integrated to save PCB space

High Side Pre-Driver

  • Allows to control a DC motor pump up to 500Hz

High Side Pre-Driver Fail Safe Switch

  • Safe MosFet turned off all the valves and the motor in case of issues

10-Bit ADC

  • ADC can monitor external or internal signals to enhance the control unit safety level

Embedded Supervision

  • Watchdog
  • Under-voltage, Over-voltage, clock fail detection
  • Open load, short circuit, Over temperature detection on each low side
  • Vds monitoring of each low side driver in real time
  • Over current and over temperature detection on the high side pre-driver

Serial Peripheral Interface (SPI)

  • Only one SPI is needed to control the device
  • MCU sent only once the current or the duty-cycle targeted through the SPI
  • MCU does not need to generate PWM signals at high frequency

Key Parametrics

  • Load Supply Voltage (Min) (V)
  • Load Supply Voltage (Max) (V)
  • Interface and Input Control
    SPI / SPI
